Choose this option if you need discreet bass in a tiny space and do not require the high power or deep rumble of the larger Thermo 12 subwoofer.
CT Sounds Hydro 12" Shallow Subwoofer
The CT Sounds Hydro 12 is a 12-inch dual 2-Ohm shallow mount subwoofer. It shares the same driver size and impedance as the Thermo 12 but has a shallower 5.39-inch depth. This makes it ideal for installations with severe height restrictions. The Thermo 12 offers 3000W max power and a 300 Oz motor for higher SPL performance. The Hydro sacrifices power handling for a more compact profile. Select this alternative if you need a 12-inch driver but have less than 6 inches of vertical space in your enclosure, accepting lower output for the sake of fit.
Skar Audio VS-10 10" Shallow Mount Subwoofer
The Skar Audio VS-10 is a 10-inch dual 2-Ohm shallow mount subwoofer. It is smaller than the Thermo 12, with a 10.7-inch width and a very shallow 4.74-inch depth.

The Skar VS-10 is designed for tight trunks where minimal depth is critical. Choose this option if your installation space is extremely constrained vertically and you prefer a 10-inch driver over the larger, more powerful Thermo 12 model.
Skar Audio VXF-12 12" Competition Subwoofer
The Skar Audio VXF-12 is a 12-inch dual 2-Ohm competition subwoofer. It matches the Thermo 12 in size and impedance but weighs 48.5 pounds, making it much heavier. Both target high SPL performance. The Thermo 12 features a 300 Oz triple-stacked motor and a 3000W max rating. The VXF-12 is built for extreme output and deep extension in competition settings.
